Three researchers from the Research and Engineering Center for Unmanned Vehicles in Colorado have created their own robot version of the old video game classic "Pac Man" to illustrate the performance of their UAV software suite.

It consists of a labyrinth drawn on the floor and 5 Roomba vacuum cleaner robots. The player can navigate the Pac Man Roomba through the labyrinth using a joystick while avoiding the other four Roombas and gaining points by vacuuming up paper scraps. Just like in the real game, a power pellet allows Pac Man to chase its opponent's ghosts and send them packing.
